Disclosed herein are compositions and methods for eliciting immune responses against antigens. In particular embodiments, the compounds and methods elicit immune responses against antigens that are otherwise recognized by the host as 'self' antigens. The immune response is enhanced by presenting the host immune system with a chimeric antigen comprising an immune response domain and a target binding domain, wherein the target binding domain comprises a xenotypic antibody fragment. By virtue of the target binding domain, antigen presenting cells take up, process, and present the chimeric antigen, eliciting both a humoral and cellular immune response.

Chimeric antigens for eliciting an immune response

Disclosed herein are compositions and methods for eliciting immune responses against antigens. In particular, the compounds and methods elicit immune responses against foreign antigens that are otherwise recognized by the host as 'self' antigens, thus breaking host tolerance to those antigens. Presenting the host immune system with a chimeric antigen comprising an immune response domain and a target binding domain, wherein the target binding domain comprises an antibody fragment, enhances the immune response against the foreign or tolerated antigen. Antigen presenting cells take up, process, and present the chimeric antigen, eliciting both a humoral and cellular immune response against the desired antigen.
